In this paper we analyze the impact of different ad hoc routing schemes on TCP traffic in multihop ad hoc wireless networks. Our hypothesis is that beyond a certain network size the uncontrolled broadcast transmission of routing messages will seriously degrade the performance of the TCP protocol. We experimentally determine the admissible operation ranges of MANETs where the level of such degra...

IEEE 802.11 MAC protocol for medium access control in wireless Local Area Networks (LANs) is the de facto standard for wireless ad hoc networks. However, it does not perform well in terms of fairness, delay and throughput specially, in multihop networks. The problem is due to both the MAC and link layer contentions. Many research papers have been published in these fields. Among them, a modific...

To determine the capacity of distributed wireless networks (i.e., ad hoc networks), the random access transport capacity was proposed as the average maximum rate of successful end-to-end transmission in the distance. In this article, we consider the random access transport capacity for multihop relaying to find the end-to-end throughput of a wireless ad hoc network, where each node relays the s...

Multimedia Support in Wireless Multihop Networks Ian D. Chakeres The network of the future will be comprised of countless cooperating wireless devices. This network will need to not only be capable of simple delay-tolerant packet delivery, but also delay and loss sensitive applications such as voice and video. To make this future a reality, new advances in the areas of wireless communication, m...

In This paper presents a novel multicast routing protocol for mobile ad hoc wireless networks. The protocol, termed ODMRP (On-Demand Multicast Routing Protocol), is a mesh-based, rather than a conventional treebased, multicast scheme and uses a forwarding group concept (only a subset of nodes forwards the multicast packets via scoped flooding). It applies on-demand procedures to dynamically bui...

This paper investigates the interworking between wireless ad hoc networks and the Internet. In other words, we consider access to the Internet via a multihop wireless network. The heterogenous communication is established with the help of specific access routers, which serve as gateways between the two kinds of networks. We describe the network scenario and its basic protocol architecture. The ...
